Technical Terms - Internet (A-Z) - JWT

What does JWT stand for?

• JavaScript Web Token

• JSON Web Token

• Java Web Token

• JSON Web Token

What is the purpose of a JWT?

• To play online games

• To send emails securely

• To share security information between two parties

• To order food online

What are the three parts of a JWT?

• Header, Body, Footer

• Header, Content, Signature

• Header, Payload, Signature

• Header, Payload, Footer

What is the purpose of the header in a JWT?

• Includes information about the type of token and algorithm used

• Includes the list of claims made by the token

• Verifies the token signature

• Includes information about the token issuer

How are the header and payload of a JWT encoded?

• Using an algorithm called base64

• Using an algorithm called base32

• Using an algorithm called base16

• Using an algorithm called base8

What is the purpose of the signature in a JWT?

• To verify that the token hasn't been tampered with

• To store user information

• To encrypt the token

• To generate the token

Why do websites and web apps use JWTs for authentication?

• To slow down the website loading speed

• To complicate the authentication process

• To reduce overhead for each user

• To increase server memory usage

How is a JWT created?

• By encoding the header and payload separately using base64

• By compressing the token

• By encrypting the entire token

• By storing the token in a database

What happens when a JWT expires?

• The user is automatically signed back in

• The token is deleted permanently

• The token becomes invalid

• The user must sign back in for a new one to be issued

What is the final step in creating a JWT?

• Hashing the combined string with a secret key to create the signature

• Appending the signature to the end of the header and payload

• Combining the header and payload strings

• Encoding the header and payload using base64
